Zero Day

A retired president is pulled back into the fray after a devastating cyberattack kills civilians and cripples critical infrastructure. Former Commander in Chief George Mullen agrees to lead a quiet, urgent effort to identify who was behind the strike. What starts as a technical hunt for servers and signatures turns into a tangled confrontation with misinformation, hidden alliances, and power plays inside government, media, and private industry. As loyalties shift and secrets surface, the operation becomes as much about truth and accountability as it is about stopping the next strike.

Created by Eric Newman, Noah Oppenheim, and Michael S. Schmidt, Zero Day premiered in 2025 and stars Robert De Niro as President George Mullen, with Jesse Plemons, Lizzy Caplan, Connie Britton, and Joan Allen in key roles. The series blends political drama with procedural elements across its episodes.

As of its initial run, Zero Day has not won major industry awards or secured high-profile nominations. Coverage has focused more on performances and topical relevance than on accolades, and any awards recognition could emerge in later seasons.

The show sparked public conversation about cybersecurity, the fragility of infrastructure, and how elected leaders respond under opaque pressures. De Niro's return to serialized television and Plemons' supporting turn have been frequent talking points, and episodes prompted debates on social platforms about information reliability and the ethical limits of surveillance.

Critical and audience reaction has been mixed to positive, with a user vote average near 7 out of 10 reflecting interest in the concept and cast. Reviewers often single out the performances and the procedural pacing while noting occasional plotting that stretches credibility. The series repeatedly tackles themes of truth, accountability, the intersection of private tech and public safety, and how memory and narrative shape political legitimacy.
